About
I am a Postdoctoral Fellow in ISyE at Georgia Tech. I received my Ph.D. in Operations Research from ISE, OSU, in August 2025, supervised by Dr. Chen Chen. I completed my B.S. in Math at Beijing Jiaotong University in June 2020.
Research
My research focuses on developing algorithms for large-scale real-world optimization problems involving decision-making under uncertainty, with applications in machine learning, power systems, and transportation.
Teaching
I have experience teaching two courses during my Ph.D. program as a teaching associate (TA), Linear Programming (Graduate Level) and Design of Experiments (Undergraduate Level). I am interested in teaching courses about mixed integer programming and computation in optimization.
